HETCOR pulse sequence design

As discussed later, the application of the SEMA sequence is not limited to the 2D PISEMA experiment, but it can be used to design a variety of sophisticated pulse sequences. For example, the selective transfer of magnetization between strongly coupled heteronuclei by SEMA is the key feature of the sequence that can be utilized in experiments such as HETCOR, H-detected experiments," and experiments to selectively measure relaxation parameters of a proton bonded to S nuclei. 

Homo-nuclear (e.g. H- H) correlation (COSY), heteronuclear ( H-X, X = 5n, F, 0,3 P) correlation (HETCOR) through- space and/or -bond dipolar coupling and nuclear interactions recorded by designed rf pulse sequences SS-NMR relaxometry...
